Abstract:
A case of soft tissue recurrence of chondroblastoma after attempted en bloc excision and endoprosthetic replacement is described. This tumor in the proximal humerus recurred after initial curettage and was subsequently treated by attempted en bloc excision with positive microscopic margins. The patient then presented with a large soft tissue recurrence surrounding the endoprosthesis. This periprosthetic recurrence necessitated re-excision and revision of the endoprosthesis. Recurrence is not uncommon following curettage of chondroblastoma. However, less is known about soft tissue recurrence after en bloc resection of this tumor with positive margins. A subset of chondroblastoma may exist with more locally aggressive behavior.
